Answer:
D) forms hydronium ions in water
Explanation:
Texture and conductivity are physical properties which makes answer A and B wrong. Answer C does not refer to a chemical reaction.
Experiments test the scientists' ideas.
Answer:
24.1g of chlorine & 15.6g of sodium
Explanation:
according to the law of conservation of mass
Na+Cl=NaCl only
The neutralization equation is:
3 Ca(OH)₂ + 2 H₃PO₄ → Ca₃(PO₄)₂ + 6 H₂O
From this equation we can see that 3 moles of Ca(OH)₂ react with 2 moles of H₃PO₄
Numbers of mmol of Ca(OH)₂ = M x V = 0.04345 x 54.93 = 2.387 mmol
Number of mmol of H₃PO₄ = 2.387 x (2/3) = 1.591 mmol
Molarity of solution = n (mmol) / V(ml) = 1.591 / 25 = 0.0636 M
This is true
Because when water evaporates molecules break and separate into different atoms
